Vertical Door Latch Assembly with Electro-Mechanical Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock systems for vertically opening doors, such as rollup or overhead doors, lack efficient and secure access control solutions, particularly in self-storage centers where multiple users require secure access.
Innovation Solution
A vertical door latch assembly with an electro-mechanical locking system that includes a bolt with a catch portion, a latch with a retention feature, and an electro-mechanical actuator. The system is controlled by a controller that directs the locking assembly between locking and non-locking positions, allowing for secure and remote access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional keyed locks are used for vertically opening doors, then basic access control is provided, but security and convenience are insufficient for multi-user environments
Solution Approach 1:
The patent replaces traditional mechanical keyed locks with an electro-mechanical locking system that uses an electro-mechanical actuator to engage and disengage the latch. This substitution enables electronic access control while maintaining mechanical security, allowing multiple users to access storage areas through electronic keys or codes without requiring physical key duplication.
Solution Approach 2:
The electro-mechanical locking system provides multi-functionality by supporting multiple access methods (electronic keys, codes, remote access) while maintaining a single unified locking mechanism. The system can serve multiple users and storage areas through a centralized control system that manages access rights for different users.
2Extent of automation
If electro-mechanical locking assemblies are added to provide secure access control, then security and remote access are improved, but device complexity increases
Solution Approach 1:
The patent merges the electro-mechanical actuator directly with the existing latch mechanism, combining the electronic control components and mechanical locking elements into a single integrated assembly. This merging approach enables remote access control functionality while minimizing the increase in overall system complexity by utilizing and integrating with existing door hardware components.

Function Achieved in This Case
The system provides secure and remote access control for vertically opening doors, enhancing security and convenience by allowing users to control access electronically, reducing the need for traditional keyed locks.
Implementation Method 1
an electro-mechanical locking assembly that has an electro-mechanical actuator for engaging the latch
Implementation Method 2
the cam engages the at least one flexible finger to flex the at least one finger between the locking position and the non-locking position

AI summary
A vertical door latch assembly includes a bolt that has a catch portion located adjacent a distal end of the bolt. A latch has a retention feature for engaging the catch portion of the bolt. An electro-mechanical locking assembly secures the latch between a locking position preventing movement of the bolt and a non-locking position allowing movement of the bolt. A controller is in electrical communication with the electro-mechanical locking assembly and is configured to direct the electro-mechanical locking assembly between the locking position and the non-locking position.
